Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a rotating body is used for atomization by centrifugal force, then liquid atomization is achieved, but the device structure becomes complex due to rotation mechanisms
Solution Approach 1:
The invention extracts and eliminates the complex rotating mechanism from the atomization system. Instead of using a rotating body to generate centrifugal force, the patent employs a stationary porous body where liquid is supplied and atomized through pressure differential, thereby achieving atomization without mechanical rotation components
Solution Approach 2:
The invention replaces the mechanical rotation system with a pressure-based fluid system. Instead of using mechanical centrifugal force from rotation, the patent uses pressure differential (positive pressure from liquid supply and negative pressure from gas flow) to achieve liquid atomization through the porous body
2Manufacturing precision
If an ultrasonic vibrator is used to generate cavitation, then liquid atomization is achieved, but an electric circuit for driving the vibrator is required
Solution Approach 1:
The invention extracts and eliminates the ultrasonic vibrator and its driving electric circuit from the atomization system. Instead of using ultrasonic cavitation, the patent employs a passive porous body structure where atomization is achieved through pressure differential and gas flow, removing the need for active ultrasonic components and their control circuits
Solution Approach 2:
The invention replaces the ultrasonic vibration system with a pressure-based fluid dynamics system. Instead of using ultrasonic waves to generate cavitation, the patent uses pressure differential (positive liquid pressure and negative gas pressure) to drive liquid through the porous body and generate atomization
3Productivity
If a nozzle is used to spray pressurized liquid, then liquid atomization is achieved, but variations in particle diameter occur
Solution Approach 1:
The invention employs a porous body with controlled pore structures (including micropores and mesopores) to achieve liquid atomization. The porous structure provides numerous uniform pathways for liquid flow, ensuring consistent droplet formation and particle diameter distribution, unlike conventional nozzles that suffer from flow instability and variation
Solution Approach 2:
The porous body acts as an intermediary structure between liquid supply and gas flow. It provides a controlled interface where liquid is distributed through numerous uniform pores, and gas flows through to atomize the liquid, ensuring consistent atomization performance and particle diameter
